Enter the number of glasses (bier, wine or spirit) you have drunk and
alcootest will estimate your BAC according to your gender and weight. You then

drive in most countries. Contrary to most other BAC applications, this one
takes into account the time of drinks and if you have eaten or not, leading to
a more precise estimation.
